TYPE-WRITING MACHINE.

To all whom it may concern:

Be it known that I, ALFRED G. F. KUROW- SKI, a citizen of the United States, residing in Brooklyn borough, in the county of Kings, city and State of New York, have invented certain new and useful Improvements in Type-VVriting Machines, of which the following is a specification.

My invention relates to attachments for platens of typewriting machines, and more particularly to a holder adapted to beapplied to a rotary platen for holding cards, address-stencils and the like. a

An object of the invention is to provide a suitable holder for stiff cards or forstencil blanks adapted to be stenciled for use in connection with an addressograph; such stencils usually being provided with a border of stiff cardboard.

The holder consists of two members formed to surround the platen and connected by a hinge extending lengthwise of the holder and platen.- The free edge of one of said members is formed into a bearing for a longitudinally slidable locking bar'carrying pins adapted to enter inclined or cam slots formed in the free edge of the other 1 member. When the pins are in position in the slots, the locking bar is moved longitudinally to cam the two members of the holder together and clamp it on the platen. The holder is provided with curved guides to receive a card or stencil blank. v Other features and advantages of vention will hereinafter appear.

In the accompanying drawings, Figure 1 illustrates my invention applied to the platen of an Underwood typewriting machine. Fig. 2 is a perspective view of the holder detached from the platen. Figs. 3 and 4 are detail views of the clamping device for the holder,

the inand showing the latter respectively in re-' leased and clamped position. Fig. 5 is a sectional end elevation view of the holder and also shows a stencil blank partially inserted into the holder.

' be operated by the usual line-space mechanism. The work holder comprises members 8 and 7 forming, respectively, a holder portion and a clasp or keeper portion therefor, both; curved to conform to the surface of Specification of Letters Patent.

the platen and connected by a hinge 9. The free edge of the member 7 provides a socket or guideway in which is slidable a locking bar 10 extending longitudinally of the holder, and having its ends 11 bent upward to form thumb pieces. The guideway for this bar may be formed by bending the free edge-12 of the member Tback upon itself. Secured to the bar 10 are looking pins 13 adapted to enter or project through inclined slots 11 in the free edge of, the member 8. When the locking bar 10 is moved to the left, as shown in Figs. 2 and 3, the holder may be placed on the platen and the pins 13 extended through the slots 14 and the locking bar moved to the right to cam the two members of the holder together, thereby clamping them to the platen.

Fig.4 indicates the holder and locking bar in clamped position. The pins 13 may be headed if desired toprevent accidental guide may be in the form of an outwardly curved lip 18, to permit the ready insertion of the card. Between the guides 15, the holder is cut-away or formed with an open space 19, exposing the area of the card which is adapted to be written: upon.

In Fig. 5 is shown a stencil card or blank comprising a body 20 of thin sheet material suitable for being stenciled, and a border 21 of heavier material such as cardboard. This stencil is shown partly inserted in the holder. When fully inserted, the lower edge of the stencil or card may rest against the hinge 9-which forms a stop therefor. In this position the stencil covers the opening 19, so that an address or other legend may be stenciled thereon; the type 22 operating in the usual well-known manner. In stenciling addresses or writing on cards, or similar work, the wear on the laten is centered in a rather small area. e present invention, however, permits the position of the. holder to be readily changed, so that the wear may be more evenly distributed. The position of the holder is changed by simply drawing the locking bar to the left, thereby loosening the holder, and then giving the latter a slight turn and returning the locking bar. A new surface or printing area is thus presented to the type. The holder is also adapted for adjustment longitudinally-of the platen. The holder may also be quickly removed entirely from the platen by spreading the two members on the hinge 9, and withdrawing the holder in a direction perpendicular to the platen axle.

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.
